CONCORD (AP) — A former New Hampshire youth baseball coach and hockey coach convicted of sexual exploitation of a child and possessing child pornography has been sentenced to 40 years in prison.

Concord police said 58-year-old Robert Joubert was charged following an investigation that began after police in York, Maine, received a complaint alleging he had engaged in sexual contact with minors.

Detectives say Joubert was involved in multiple sexual assaults in Concord from 1995 and 2004. Police say all the victims were juvenile males.

Joubert of Manchester was found guilty in November. Court documents say the victims were under age 13 at the time of the abuse.

WMUR-TV reports Joubert was sentenced in federal court.

U.S. Attorney John Kacavas said the 60-year-old Joubert ran the Seacoast Baseball Academy in York, Maine, where the investigation began in March 2012. Police found numerous young men who said Joubert abused them.
